For a long time, storage was getting cheaper all the time but we've hit scaling walls in both CPUs and drives. I remember when I was a kid and bought Mechwarrior 2 a game that could use up to 500mb! The guy working the video game locker warned me "are you sure you have enough hard drive space?" after having just bought a 2gb drive for like $60, or something, I don't remember exactly. A concern that would have been valid maybe a year earlier.
